EXECUTIVE SUMMARY A survey of a number of schools in a number of different climates was carried out to determine the condition of building components of interest in the project. Schools in Melbourne, the Victorian Surf Coast, Brisbane, Townsville and the Sunshine Coast were inspected. A rating system was devised to categorise the components and the results collated in tables. Analysis of the data (where sufficient examples permitted) resulted in formulae to predict the service of the components and a database was derived.

1 INTRODUCTION This project is developing a program to access a number of sources of data on service lifetimes of metallic building components. Originally it was planned to utilise the Queensland Department of Public Works database of maintenance activities to develop a lifetime database giving information based on current usage and updating as more events were entered by the actual maintainers reflecting ongoing upkeep of the schools’ infrastructure. Maintenance information is seen as being a particularly useful source of data about service life of building components as it relates to actual performance of materials in the working environment. Access was granted to a number of databases recording maintenance activities in Queensland Government Housing. However, analysis of the information indicated that entries did not give information in fine enough detail to enable extraction of data for the individual building components being considered in the current work. An alternative approach was devised to estimate the performance of materials in the field. This involved a survey of a range of schools with inspection of the building components of relevance to the current work. These were given a rating indicating the current condition of the structure and the age of the buildings was also ascertained. This data collected was also used to validate the modifications made to the holistic model for the different building components.

2 SURVEY METHODOLOGY Schools were chosen to give a wide range of climates and corrosivity levels (related to salt levels). At least three schools in each category were chosen, where possible with different ages. Three climates were looked at:

• Tropical (Townsville) • Subtropical (Brisbane and Sunshine Coast) • Temperate (Melbourne and southern coast of Victoria)

Figure 1 shows the locations of the school areas surveyed in the Eastern part of Australia. Within these climates corrosive severity levels can be classified as

• Severe marine (within 3km of the coast) • Coastal (3-10km from coast) • Inland (>10km from coast)

Ideally all three corrosivity levels in each of the three climate types would be surveyed, but this was not possible. The categories looked at are:

• Tropical Coastal • Subtropical Marine • Subtropical inland • Temperate Marine

• Temperate Inland

Figure 1. Locations of the different areas surveyed, chosen to give a range of climates

The Sunshine Coast schools surveyed are shown in more detail in Figure 2. A number of schools were looked at in 2005 as part of the earlier phase of this project and they are indicated in the map as well. The locations of the Townsville schools are shown in Figure 3 and those of the Victorian schools surveyed in Figure 4. A list of all the Queensland schools surveyed is given in Table 1 along with details such as longitude and latitude and distance from the ocean. In some cases two figures are given indicating the distance from a sheltered beach on an inlet and the actual distance from the nearest ocean beach. Similar details are given for the Victorian schools visited in Table 2. Not all the schools visited had the full array of metal components of interest. In particular it was difficult to gain information for the sub-floor components, as many schools had wooden and concrete footings rather than metal. These were more prevalent on portable classrooms but they were not included in the survey as their location history is unknown and the condition of metal components may have been affected by previous environments. At each school, the relevant building components on a number of buildings were identified as to material and the condition rated, noting the orientation and degree of sheltering etc. Photographs taken are documented in a series of appendices (I –XXVII) in separate files (due to the size).

2.1 Material Rating Used in Survey The components in the survey were rated using the following scheme:

0. As new 1. Shows signs of age 2. Needs maintenance 3. Significant maintenance required 4. Planning for replacement 5. Needs replacement

How these different categories relate to the conditions of the components is detailed in Table 3. Indicative photos depicting the condition of the components are shown in Figure 5 (on the following pages). Not all ratings for each component were found or photographed in the survey.

3 SURVEY RESULTS The raw data for all the schools surveyed is presented in Appendix XXVIII. The data has been reformatted in Tables 4 -11 which show the ratings for the different components categorised for the different environments. The information for Colorbond roofs is graphed in Figure 6.

3.1 Analysis of Data The data for the different components were graphed separately for each material and environment type. In some cases there were very limited data points, but the points were used to estimate an exponential line of best fit using the equation: Damage = A * ln(life) – B …Eqn (1) Where Damage is the rating system (from 0-5) life is the age of the component in years A, B are constants In some cases there appeared to be two rates of material aging so these were separated in two sets of data: “normal” and “accelerated”. Equation 1 was used to estimate the service life of all the components surveyed. A and B were determined for the different materials and environments. 3.1.1 Colorbond® Components For Colorbond® the formula was used to estimate the time to reach Rating 3 and then 10 years was added. Table 12 shows the values estimated for A and B from the survey data. Table 12. Parameter Values for Colorbond® components Component Environment A BRoof Normal 1.27 -1.84 Roof Accelerated 1.30 -0.38 Roof Tropical 1.18 -1.5 Roof Tropical acclerated 1.3 0 Downpipes normal 1.13 -0.95 Down pipes accelerated 1.39 0 Gutters normal 1.2 -1.9 Gutters tropical 0.99 -0.043 Gutters acclerated 1.30 -0.67 3.1.2 Zincalume Components Equation (1) was used to calculate the years to reach Rating 3 and then D was added to give service life. Values for A, B and D are given in Table 13. Table 13. Parameters for Zincalume components Component Environment A B D Roof Sub tropical normal 1.28 -1.80 9 Roof accelerated 1.28 -0.50 9 Roof tropical 1.28 -1.43 9 Roof temperate 1.28 -1.43 9 Downpipes normal 1.25 -2.2 9 Down pipes accelerated 1.31 -0.37 6 Gutters normal 1.26 -1.29 9 Gutters accelerated 1.31 -0.075 6 Ridge cap normal 1.18 -1.2 9

3.1.3 Galvanised Components Equation (1) was used to calculate the years to reach Rating 3 and then D was added to give service life. Values for A, B and D are given in Table 14. Table 14. Parameters for Galvanised components Component Environment A B D Roof normal 1.1 -0.64 8 Roof accelerated 1.3 -0.48 8 Downpipes normal 1.1 -1.58 8 Down pipes accelerated 1.31 -0.37 5 Gutters normal 2.52 -4.9 8 Flashing normal 1.1 -1.1 8 Flashing accelerated 1.22 -0.18 8 Fasteners normal 1.36 -1.1 * Fasteners accelerated 1.38 -0.06 * * For fasteners the formulae were used to calculate the time to reach Rating 5 to give the predicted service life. Therefore D is not applicable 3.1.4 Aluminium Components Equation (1) was used to calculate the years to reach Rating 3 and then D was added to give service life. Values for A, B and D are given in Table 15. Table 15. Parameters for Galvanised components Component Environment A B D Windows normal 0.92 -0.68 10 Windows accelerated 1.0 -0.04 10 Powder coated normal 0.53 -0.05 10 Powder coated accelerated 0.89 -0.14 10 Fasteners normal 1.36 -1.1 5 Fasteners accelerated 1.36 -0.06 5 3.1.5 Database The results of applying these formulae to the components surveyed to estimate the remaining life is consolidated into Table 16. Service life determined to be more the 50 years is quoted as >50 in all cases.
